8 The value of Planck's constant is 6.63 x 10-34 J-s. The
speed of light is 3x10 nms-7. Which is closest to the
wavelength in nanometer of a quantum of light with
frequency of 6 x 1015s-??

★ FREQUENCY = h × c / lambda(wavelength)
★ LAMBDA = h c / f
= 6.6 × 10^-34 × 3 × 10^10 / 6 × 10^-15
= 6.6 × 10^-24 / 2 × 10^-15
= 3.3 × 10^9
= 3.3 nanometer
★ ANSWER :-- APPROX... 10 nm... option A
